That's a fair criticism of me using a lazy shorthand, but it really is quite difficult to capture the level of vitriol against Musk. It's at a level I've never seen against anyone in my lifetime. People certain express strong hatred towards him than, say, Putin or Xi.
Obviously in reality Musk has done nothing to be compared to Hitler, however as far as how much hate he gets in 2022, I would say he easily surpasses Hitler by at least a factor of a thousand. Very few people even talk about Hitler anymore, so it doesn't really capture the sense of hate either.
I think a good comparison in the US would be Trump and I think more people hate Trump than Musk.
